For example in your training and testing data, you need the same shape, so that you should try something like,
mean = np.mean(X_train_features, axis=0)
std = np.std(X_train_features, axis=0)
X_train_features = (X_train_features - mean)/std
Here X_train_features can be a data frame of spectrogram or mfcc features....
